Abstract: A module (100) for a system for the laying of underground and railroad and tram lines both in tunnel and on the surface, in particular railroad and tram lines, comprising a supporting slab (101) for the tracks (6), with substantially parallelepiped shape, the slab having at least four peripheral housings (1), passing from the extrados to the intrados and suitable to house respective adjustable levelling devices (120).

Abstract: A rail support block assembly includes a resilient member and a molded block having a top, a bottom and peripheral wall. The block is adapted for fastening one or more rails on the top. The prefabricated resilient member has an outer tray and inner tray arranged within the outer tray, and includes a resilient intermediate structure between the trays. The block is molded. The block is fixed in the inner tray to extend under the bottom of the block and along a lower region of the peripheral wall. The resilient member may form a part of the block mold, so that a mold member combined with the resilient member delimit the mold for the block. The moldable material is introduced and adheres directly to the inner tray of the prefabricated resilient member.

Abstract: A prefabricated module (1) to be used in constructing a track for an urban transport vehicle. The module comprises an integral carrier structure (2) made of concrete and comprising two side sills (4) having an upper surface (5), used as a driving pathway for the vehicle wheels, and connecting crossbars (8) which connect and retain the sills substantially parallel to each other. The lower surfaces (6, 39) of the sills and crossbars are ground-bearing surfaces. A guiding rail section (3), mounted on the carrier structure, is preferably symmetrical, has an I section and a lower portion coated with a liner material (13). The modules, whether rectilinear or curved, are to be placed on an existing road layout or in a trench with a compacted bottom, and are connected one after the other to form the driving track.

Abstract: The invention relates to track system having two substantially parallel tracks (6) which are disposed on respective concrete slabs (1) of a fixed track. The slabs (1) comprises a plurality of track supports (2, 2?) for receiving and fastening thereon two parallel rails (5). The top surfaces (3) of the slabs (1) of the two tracks (6) are inclined independent of the a guiding system of the tracks (6) and of the corresponding position of the rail supports (2, 2?) relative to the two outer sides (8) of the track system and form a slope. The invention also relates to a concrete slab of a fixed track, which comprises supports (2, 2?) for the first rail (5) which are higher in relation to the top surface (3) of the slab (1) than the supports (2, 2?) for the second rail (5).

Abstract: A rail cover and support for mounting and insulating the rails of an electric transit system in which the rail cover is vulcanized both to the rail and outer skid support at the manufacturing site prior to delivery to the field and a rail cover completely surrounds both the base flange and web portion of each rail and terminates along the undersides of the top flange. In one form, the upper free ends of the rail cover are increased in thickness to form bumpers along opposite sides of the rail to cushion it against undue shifting or vibration. In fabricating the rail, a sheet dielectric material is vulcanized to the rail with or without a skid plate.

Abstract: A method of constructing a rail track in which a concrete track slab is produced and rail track anchor members are inserted in the track slab by an inserter system mobile along the route of the rail track includes the following steps: using a machine for continuously pouring concrete to produce two concrete walls laterally delimiting the edges of the track slab to be poured; pouring the concrete track slab between the walls; and using the inserter system to insert anchor members in the freshly poured track slab, the tie plate inserter system being adjusted accurately by a measuring station, topographical survey points, a measuring system, and reflectors carried by the inserter system.

Abstract: A method for producing a rail substructure for railroad tracks, for which a rail bed is concreted and dowels are anchored positively in the concrete in order to fasten the rails, such that the dowels are inserted into the still deformable concrete during the concreting of the track bed.

Abstract: The invention relates to a method for the continuous laying of a rail (4,4′) on a rigid track, in particular consisting of precast concrete components (1). According to said method, the rail (4,4′) is positioned in a channel (3,3′) of the rigid track and is fixed by said channel (3,3′) being filled. The inventive method is characterised in that chamber filler blocks (30) are located at the sides of the rail (4,4′) and the gap (32) between the chamber filler blocks (30) and the sides (34) of the channel is filled with a grouting mortar.

Abstract: A method of constructing a rail track on a track-receiving concrete slab provided with channels serving to receive the rails of the rail track, wherein, after the concrete forming the track-receiving slab has set, it comprises at least the following steps: a) the stretches of rail are put in place above the channels in the track-receiving slab, each rail having a foot coated with a casing of resilient material; and b) the foot as coated with its casing is inserted into the channel by force.

Abstract: A rail arrangement includes a bullheaded rail having joint ties and a rail head, a rail bridge and a rail foot. There is a driving track made of concrete with an integrated joint, in which the rail is seated in connection with a substrate; as well as profiles made of elastomeric material. The profiles includes a base profile arranged below the foot of the rail and which has flanges on both sides which completely or partially grip around the foot of the rail. The base profile has a plurality of channels having a rhombic cross-sectional shape and extending in the longitudinal direction of the rail, which are arranged in the plane extending parallel with the underside of the foot of the rail. The channels at the edges of the base profile have a smaller cross sectional shape than the channels at the center area. There are two side profiles abutting the rail on both sides. One of the side profiles preferably has a tracking groove on the side of the wheel rim. There is also a joint tie coating.

Abstract: A precast concrete curved grade crossing includes a plurality of base members, each of which has a central recess formed in the upper surface thereof. The central recess receives a plurality of center panels. The plurality of base members and center panels are laid end-to-end to form a curved crossing. Each of the plurality of base members and center panels have a substantially trapezoidal shape which varies in dimension proportional to the radius of curvature of the crossing. A restraining rail is removably attached to a first standard rail, both being received between the base members and center panels to add rigidity and structural stability. The first standard rail together with the restraining rail are encased by a wide rubber boot which extends through the crossing in a single continuous piece to maintain electrical isolation between the concrete base member and center panels and the first and restraining rails.

Abstract: A rigid concrete slab for conveying vehicular or railroad traffic which is provided with functional longitudinal beams that extend or protrude downward from the underside of the slab and are fully and continuously supported by the underlying material. The attached beams enhance, strengthen and stabilize both longitudinally and transversely. Friction and suction, or interface adhesion, between the beams and the underlying material in which it rests causes the beams to act as anchors thereby further resisting displacement or distortion of the slab.

Abstract: A modular railway crossing element is described having a slab member with a pair of open channels formed in its upper surface. The channels are substantially parallel and dimensioned to receive a pair of rails. Also described is a railway crossing utilizing the slab member and a method of forming a railway crossing.
